DOTX at a glance
DOTX
Convert to DOTX when the goal is a reusable Word template for future document creation, such as branded reports, letterheads, forms, policy shells, or proposal frameworks.
It is the right target when recipients should start from a controlled structure rather than edit a finished document directly.
Choose DOTX over DOCX when template semantics are the point of the file.
AC3 at a glance
AC3
Convert to AC3 when the output is intended for surround-capable consumer playback, especially DVD, broadcast, legacy streaming hardware, or home-theater distribution.
It is a strong target for 5.1-compatible delivery where broad device support matters more than lossless fidelity.
For mastering or archival preservation, lossless formats are usually better.
